CVE-2026-35514 Details
Description
Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. In version 4.9.0, the endpoint POST /user/invited does not validate any invite token, authentication header, or session. Any unauthenticated attacker can call this endpoint directly to create a fully active account and receive a valid JWT — even when the instance has existing users and signupRestricted is enabled. This bypass is distinct from the normal registration endpoint (POST /user) which enforces signupRestricted and sets active: false pending verification. This issue has been patched in version 5.0.0.
A vulnerability in Chartbrew version 4.9.0 allows unauthenticated users to create active accounts by exploiting the /user/invited endpoint, which lacks proper validation of invite tokens, authentication headers, or user sessions. This issue arises even when the signupRestricted feature is enabled and the instance has existing users. The vulnerability has been addressed in version 5.0.0.
Users can update to Chartbrew version 5.0.0, where this vulnerability has been patched.
